The youngster has hinted she could return to the college in the United States this summer, meaning she will not be available for next year’s edition.
Mitchual was a revelation at the 2013 edition of the competition where she inspired St Mary’s to their first finals with breathtaking skills at the centre court of the Aviation Social Centre.
The power forward was being courted by a number of high-profile schools including giants Wesley Girls Senior High.
But she has delivered the ultimate sucker punch to the ambitions of the Cape Coast-based school by confirming she may not be able to feature in the competition again.
She posted on her facebook wall: “Hello everyone this is Ama. Thanks for your comments it meant so much to me unfortunately this will be the last time I will be able to play in the Sprite ball competition.
“I had so much fun in it even though i didn’t get MVP just playing was the best thing.”
Mitchual missed out on the MVP award after she lost the individual accolade to Aggrey Memorial’s Matilda Gordon.
